+\wxheading{wxTextCtrl text format}
+
+The multiline text controls always store the text as a sequence of lines
+separated by {\tt $\backslash$n} characters, i.e. in the Unix text format even
+on non-Unix platforms. This allows the user code to ignore the differences
+between the platforms but at a price: the indices in the control such as those
+returned by \helpref{GetInsertionPoint}{wxtextctrlgetinsertionpoint} or 
+\helpref{GetSelection}{wxtextctrlgetselection} can {\bf not} be used as
+indices into the string returned by \helpref{GetValue}{wxtextctrlgetvalue} as
+they're going to be slightly off for platforms using 
+{\tt $\backslash$r$\backslash$n} as separator (as Windows does), for example.
+
+Instead, if you need to obtain a substring between the $2$ indices obtained
+from the control with the help of the functions mentioned above, you should
+use \helpref{GetRange}{wxtextctrlgetrange}. And the indices themselves can
+only be passed to other methods, for example 
+\helpref{SetInsertionPoint}{wxtextctrlsetinsertionpoint} or 
+\helpref{SetSelection}{wxtextctrlsetselection}.
+
+To summarize: never use the indices returned by (multiline) wxTextCtrl as
+indices into the string it contains, but only as arguments to be passed back
+to the other wxTextCtrl methods.
